CAN-SEALING APPARATUS.

Specification of Letters Patent. Patented Sept. 1'7,

Application filed March 21, 1918. Serial No. 223,735.

To all whom it may concern:

Be it known that I, RUPERT R. SmLnY, a citizen of the United States,residing at Atlanta, in the county of Fulton and State of Georgia, haveinvented certain new and useful Improvements in Can-Sealing 'Apparatus,of which the following is a specification.

This invention relates to a machine or an apparatus adapted for use insealing cans and more particularly of the small portable type suitablefor home use.

One of the objects of the present invention is to provide a simple andpractical can sealing machine 01 apparatus of light portableconstruction which may be easily operated for sealing cans of a certaintypenot requiring the use of solder. A further object is to provide anapparatus of the above general character suitable for home use andcapable of various adjustments and having interchangeable parts wherebycans of different sizesmay be operated upon. A further object is toprovide a machine of the above general character, having relatively fewparts whichma-y be inexpensively manufacand assembled and which will notbe likely to get out oforder when in use.

provide a machine of the ciently operating upon the cans of that typehaving interlocking flange features.

Other objects will be in part obvious from the annexed drawings and inpart indicated in connection therewith by the following analysis of thisinvention. A This invention accordingly consists in the features ofconstruction, parts and in combination of the unique relations of themembers and in the relative proportioning and disposition thereof, allas more completely outlined herein.

M to comprehend r "the numerous modifications in structure and To enableothers skilled in the art so fully the underlying features thereof thatthey may embody the same by relation contemplated by this invention,drawings depicting a preferred form have been annexed as a part of thisdisclosure, and in such drawings like characters of reference denotecorresponding parts throughout all the views, in which Figure 1 is aside elevational view of the complete machine;

'Fig. 2 is a detall plan view showing the be understood The presentinvention is. designed more particularly as. an improvement over thatform of device shown in my co-pending application, Serial Number195,378, filed October 8, 1917, for'can seaming machines.

Referring now to the drawings in detail,

5 denotes any suitable form of base member means whereby it may besecurely anchored or fixed in relative position'as upon a table, forexample, and from which base project two uprights 6 and 7 having afitting 8 at the upper end secured thereto by meansof set screws 10 for"holding the same in fixed and adjusted position. This fitting isproadapted ,to be provided with fastening' vided wlth a laterallyextending arm 11 in which is mounted a shaft 12 adapted to be rotated inany desired manner by means of handle 13. V

Interposed between the base and fitting 8 is a second fitting or member14 embracing both rods or supports 6 and 7 and split at one side wherebythe same may be clamped in adjusted position by means of set screws orclamping means 15 which when tightened will gripthe rod6 and hold thepart in any desired vertically adjusted position.

Thisfitting 1 1 carries a laterally extending arm 16 similar to the arm11 and is provided at its outer end with a shaft 17 carry ing a table 18for supporting the can while being sealed or seamed. It is, of course,to

that this table 18 is interchangeably connected with the shaft 17 in anydesired manner for supporting cans of different; size. Mounted uponthe'shaft 17 is a leverl 20 having a cam member2l adapted to coact withafixed cam member 22 upon the arm 16in such a manner that as the handleor lever 20 is given a quarter turn -the cam surfaces 21 willrideupwardly upon the cam surface 22 thereby moving the table 18relatively upwardly to bringthe can into sealingfposition as willhereinafterfully be explainedff q V I The lower part of the shaft 12 isprovided with a disk 23 which may be easily and quickly separated fromthe shaft 12 in any desired manner as will appear obvious to thoseskilled in the art and the disks of larger or smaller size substitutedtherefor according to the size of the can to be operated upon. The cansand their covers are preferably of that type illustrated in my abovereferred to pending application in which the cover member is providedwith a depressed central portion adapted to be engaged by the disk 23and forced clownwardly into position within the container when the tableis raised. Both the container and cover are provided with registeringflanges which are engaged by the seaming or sealing mechanism now aboutto be describedandto be folded over one upon the other and pressed downinto firm interlocking engagement.

This seaming orsealing mechanism is preferably carried by a fitting 25mounted upon the fixed supports 6 and 7 and connected by means of anadjusting device 26 whereby it may be adjusted vertically upon thesupports to any desired degree to pernnt proper alinement of thecoacting sealing rollers with disk 23. This member 25 is provided with alaterally extending arm 27 having at its end a guide 28 upon which isadjustably mounted a block 30 adapted to be held in any desired adjustedposition by means of bolts or fastening devices 31. The block 31 has acentral pivot 32 supporting a segment 33 having gear teeth 34: upon oneside thereof adapted to be engaged by a worm gear 35 rotatable in anysuitable way as by means of hand wheel 36 extending to one side of theblock 31. It will thus be seen that as the wheel 36 is turned, thesegment 35 will be rotated either in one direction or the other aboutthe pivot 32 to bring rollers 37 and 38 into or out of'engagement withthe disk 23. These rollers and disk are substantially the same asillustrated and described in my above referred to application and areprovided with coacting flanges and recesses whereby as the handle 13 isturned the can carried by the disk 23 will also be rotated and theflanges of the cover and can will first be crimped or rolled one uponthe other by the roller 38 after which the rolled portion will be firmlypressed down by means of the roller 37.

It is believed from the above description that the operation of thismachine will be clearly understood. It may be stated, however, that inoperation the disk 23 and table 18 are selected according to the size ofthe can to be operated upon and put in can is then placed upon the table18, assuming the necessary vertical adjustments to havebeen made, andthe cover applied after place 7 upon the respective shafts l2. and '17.The

which the lever 20 is given a quarter turn to cause a relative upwardmovement of the table 18, thus pressing the cover firmly into place. Thehand wheel 36 is then turned to bring the roller 38 into engagement withor tangential to the disk 23. With the parts in this position, theoperator then turns the crank 13 one or more times as may be necessaryto insure the engaging flanges of the cover and body member to be rolledinto position after which the hand wheel 36is then turned in theopposite direction to bring the roller 37 into engagement with therolled or turned over flanges, whereupon the crank 13 is given anotherturn thereby to firmly press down the rolled over flanges of the coverand body portion of the can. After this operation the lever 20 is movedin the opposite direction which causes a relative downward movement ofthe table and permits the removal of the can therefrom and the insertionof the next can to be operated upon.

It is, of course, to be understood that different size tables ordisks 23are substituted as may be necessary according to different sizes of cansand when this occurs, it'is frequently necessary to make properadjustments in the relative distance between the table 20 and disk 23.This is most easily accomplished by loosening the single adjustingdevice 15 which permits the table 18 and associated parts to be movedthe desireddistance.

It will be seen from the above description that the present inventioncomprises a simple and practical can seaming or sealingapparatusof'light portable construction which renders it particularly adapted forhome use. The parts composing the apparatus are relatively few in numberand may be easily and inexpensively manufactured and assembled. Inshort, the invention is believed to accomplish, among others, all of theobjects and advantages herein set forth.

I realize that considerable variatibnispossible in the details ofconstruction and arrangement of parts without departing from the spiritof'my invention, and I therefore do not intend to limit myself to thespecific form shown and described.

Having thus described my invention what I claim as new and desire tosecure-by Letand hand mechanism for bringing one or the other of saidseaming rollers into operation at will.
